1. method of analyzing Chinese medicine dimethyl sulfoxide (DMSO) extract with nuclear magnetic resonance technique, it is characterized in that:

  • the preparation need testing solution, take by weighing Chinese crude drug or Chinese medicine preparation in accordance with regulations, and carry out pre-treatment, substitute former extractant by same the extraction dosage of stipulating down with dimethyl sulfoxide (DMSO), under 18.45 ℃



    189 ℃

    temperature, the extracting method commonly used with Chinese medicine extracts, filter, be need testing solution, adopt nuclear magnetic resonance apparatus system commonly used, select each systematic parameter according to nuclear magnetic resonance apparatus system and Chinese medicine characteristic, the need testing solution qualitative, quantitative is measured its ingredient, thereby obtained comprising the Chinese medicine all the components at interior nmr spectrum, molecular structure and physical characteristics.
